NOTE! PREVENT GENERATION OF MISTS!

Route of Exposure

Symptoms

First Aid

Inhalation Dizziness. Drowsiness. Unconsciousness. Fresh air rest. Artificial respiration if indicated. Refer for medical attention.
Skin Redness. Pain. Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Redness. Pain. First rinse with plenty of water for several minutes (remove contact lenses if easily possible) then take to a doctor.
Ingestion Abdominal pain. Sore throat. (Further see Inhalation). Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Rest.
Notes for ICSC Information
Depending on the degree of exposure periodic medical examination is indicated. An added stabilizer or inhibitor can influence the toxicological properties of this substance consult an expert. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT use in the vicinity of a fire or a hot surface or during welding.

1. PAN Bad Actors are chemicals that are one or more of the following: highly acutely toxic, cholinesterase inhibitor, known/probable carcinogen, known groundwater pollutant or known reproductive or developmental toxicant. NOTE! Because there are no authoritative lists of Endocrine Disrupting (ED) chemicals, EDs are not yet considered PAN Bad Actor chemicals.

Summary of Acute Toxicity for Organism Group

Sorry, no honeybee acute toxicity data available for this chemical. Try related chemicals.

Note: Population-level effects on honeybees may occur even if a pesticide has low acute toxicity. For example, certain pesticides interfere with honeybee reproduction, ability to navigate, or temperature regulation, any of which can have an effect on long-term survival of honeybee colonies. The neonicotinoids, pyrethroids and keto-enol pesticides are some types of pesticides causing one or more of these effects.
Honeybee Chronic Toxicity

Any underlined term with a book icon has additional information.

* Data marked with an asterisk indicates that this chemical is not explicitly listed on the corresponding list. Instead, it belongs to a group of chemicals that IS designated on the list. For example, if an agency assigns a classification of reproductive toxicant to "mercury compounds", that classification is applied to all mercury compounds in the PAN Pesticide database, which are then marked with an asterisk.
